Creating Project Contrast: A Video Game Exploring Consciousness And Qualia, Pierce Papke
Creating Project Contrast: A Video Game Exploring Consciousness And Qualia, Pierce Papke
Honors Projects
Project Contrast is a video game that explores how the unique traits inherent to video games might engage reflective player responses to qualitative experience. Project Contrast does this through suspension of disbelief, avatar projection, presence, player agency in storytelling, visual perception, functional gameplay, and art. Considering the difficulty in researching qualitative experience due to its subjectivity and circular explanations, I created Project Contrast not to analyze qualia, though that was my original hope. I instead created Project Contrast as an avenue for player self-reflection and learning about qualitative experience. While video games might be just code and art on a …
Characterizing And Investigating The Electrophysiological Properties Of The Plastic Cricket Auditory System In Response To Cooling, Hannah Tess Scotch
Characterizing And Investigating The Electrophysiological Properties Of The Plastic Cricket Auditory System In Response To Cooling, Hannah Tess Scotch
Honors Projects
The auditory system of the Mediterranean field cricket (Gryllus bimaculatus) is capable of profound compensatory plasticity. Following deafferentation due to the loss of an auditory organ, the dendrites of intermediate auditory neuron Ascending Neuron 2 (AN-2) grow across the midline and functionally connect to contralateral afferents. The loss of the auditory organ can be mimicked with reversible cold-deactivation, in which cooled Peltier elements silence the auditory organ and its afferents. Though this would presumably prevent AN-2 from firing, cooling instead induces a novel firing pattern called DOPE (delayed-onset, prolonged-excitation). In this study, intracellular physiological recordings were completed before, …
Mechanisms Underlying Variable Responses To The Neuropeptide C-Type Allatostatin (Ast-C) Across Isoforms And Among Individuals In The American Lobster, Homarus Americanus, Audrey J. Muscato
Mechanisms Underlying Variable Responses To The Neuropeptide C-Type Allatostatin (Ast-C) Across Isoforms And Among Individuals In The American Lobster, Homarus Americanus, Audrey J. Muscato
Honors Projects
Central pattern generators (CPGs) produce patterned outputs independent of sensory input. The cardiac neuromuscular system of the American lobster (Homarus americanus) is driven by a CPG called the cardiac ganglion (CG), which is composed of nine neurons, making it a model system of study. Modulation of CPGs allows for functional flexibility. One neuropeptide family that modulates the CG is C-type allatostatin (AST-C I-III). Previous research has shown variation in the responses of the CG across the three isoforms and among individuals. First, we investigated why AST-C I and III elicit responses that are more similar to each other than they …
Responses Of Central Pattern Generators In The American Lobster Stns To Multiple Members Of A Novel Neuropeptide Family, Benjamin Harley Wong
Responses Of Central Pattern Generators In The American Lobster Stns To Multiple Members Of A Novel Neuropeptide Family, Benjamin Harley Wong
Honors Projects
Neuropeptides are important modulators of neural activity, allowing neural networks, such as the central pattern generators (CPGs) that control rhythmic movements, to alter their output and thus generate behavioral flexibility. Isoforms of a neuropeptide family vary in physical structure, allowing potentially distinct functional neuromodulatory effects on CPG systems. While some familial neuropeptide isoforms can differentially affect a system, others in the same family may elicit indistinguishable effects. Here, we examined the effects elicited by members of a novel family of six peptide hormone isoforms (GSEFLamides: I-, M-, AL-, AM-, AV-, and VM-GSEFLamide) on the pyloric filter and gastric mill CPGs …
The Relationship Between Time Of Day, Mood, And Electroencephalography (Eeg) Asymmetry, Morgan Tantillo
The Relationship Between Time Of Day, Mood, And Electroencephalography (Eeg) Asymmetry, Morgan Tantillo
Honors Projects
Previous researchers have had success in finding a correlation between exercise and an increase in positive mood. Researchers have also found a correlation between time of day and mood. The current study will explore the relationship between time of day, mood, and electroencephalography (EEG) asymmetry. The study utilized a convenient sample of ten undergraduate students at Bowling Green State University. Participants had baseline EEG recordings taken, and then participated in moderate exercise, followed by another EEG recording. Participants’ mood was assessed through a self-reported mood questionnaire before the condition as well as immediately after. Due to multiple statistical tests, the …
Anatomical Markers For Elevated Cognition In Dinosaurs, Thomas Gaetano
Anatomical Markers For Elevated Cognition In Dinosaurs, Thomas Gaetano
Honors Projects
Much research has been conducted on brain evolution within Dinosauria. Dinosaurs were originally believed to be incapable of any advanced cognitive abilities beyond the level observed in modern reptiles. This is likely true for many dinosaurs, but recent discoveries suggest that the non-avian maniraptor dinosaurs shared many physical characteristics with their bird descendants, including body feathers and neural adaptations for flight. By studying cranial endocasts (the braincase of fossilized skulls) using computed tomography (CT), paleontologists are beginning to understand the neural changes that took place across the dinosaur-bird transition. Most of these studies are focused on the development of flight, …
Dendrites Of Cardiac Ganglion Regulate Heartbeat Of American Lobster, Homarus Americanus, Through Stretch Feedback, Mara R. Chin-Purcell
Dendrites Of Cardiac Ganglion Regulate Heartbeat Of American Lobster, Homarus Americanus, Through Stretch Feedback, Mara R. Chin-Purcell
Honors Projects
Central pattern generators are neuronal networks that produce reliable rhythmic motor output. A simple pattern generator, known as the cardiac ganglion (CG), controls the heart of the American lobster, Homarus americanus. Previous studies have suggested that stretch feedback relays information to the cardiac ganglion about the degree of filling in the heart, and that this feedback is mediated by stretch-sensitive dendrites extending from CG neurons. I sought to determine the mechanisms behind this stretch feedback pathway. One hundred second extension pyramids were applied to each heart while amplitude and frequency of contractions were recorded; 87% of hearts responded to …
